Accoya has actually ended up being an industry favorite due to the fact that it is chemically customized to be dimensionally steady, indicating it does not shrink or swell with the seasons, preventing the typical "sticking" of sash windows.

When integrated with modern-day double-glazing and weather-stripping, wooden sash windows provide excellent U-values (thermal effectiveness).Property Value: Original or premium replica wood windows can substantially increase the resale value of a heritage home.Modern Features in Traditional Frames
